Studies
• Dengue – Like gatas-gatas (Euphorbia hirta), there have been anecdotal reports of the use of Ipomoea batatas in dengue, with improvement in platelet counts being attributed to decoctions of kamote tops.
Preparation: kamote tops are boiled in wate for 5 minutesr to extract the juice
• Diabetes – Despite its “sweet” name, it may be beneficial for diabetes as some studies suggest it may stabilize blood sugars and lower insulin resistance.
• Purple Sweet Potato anthocyanins have antioxidative activity in vivo as well as in vitro.
• Hemostatic mistura of ipomoea balatas leaves, methods of preparation and use thereof — a Jinshuye styptic plant preparation, an invention made from the extracts of leaf and stems of Ipomoea batatas has qi and spleen invigorating effects, cooling the blood and stopping bleeding. Such a composition has the potential of use for ITP (idiopathic thrombocytopenic purpura), radiotherapy- and chemotherapy-induced thrombocytopenia.• Local Root Crops as Antioxidant: A 2006 study of commonly consumed roots crops in the Philippines (Kamote, Ipomoea batata; ubi, purple yam, Dioscorea alata; cassava, Manihot esculenta; taro or gabi, Colocasia esculenta; carrot, Daucus carota; yacon (Smallanthus sonchifolius) showed them to be rich sources of phenolic compounds with antioxidant acitivity, highest in sweet potato, followed by taro, potato, purple yam and lowest in the carrot.
• BIOACTIVE COMPOUNDS IN IPOMOEA BATATAS LEAVES: Results suggest the total phenolic content was positively correlated with radical scavenging activities of the sweet potato leaves.
• Antidiabetic activity of white skinned sweet potato (Ipomoea batatas L.) in obese Zucker fatty rats: Results suggest the white skinned sweet potato has antidiabetic activity and and improves glucose and lipid metabolism by reducing insulin resistance.

• Flavonoids: Leaf extract study isolated five news compounds: tiliroside, astragalin, rhamnocitrin, rhamnetin and kaempferol.• Chitinases: Study identified new chitinolytic enzymes in sweet potato leaves. Chitinases catalyze the hydrolysis of chitin, the main structural component of fungal walls and arthropod integuments. Studies suggest it has other functions and has been proposed to play a role in the defense against pathogens. Chitinases are also useful in the production of biomedical and biotech products; used in the production of chitooligosaccharides, glucosamines and GlcNAc. Other applications are found in mosquito control and pathogenic plant fungi control.• Antioxidant / Antiproliferative: Study demonstrated that the phytochemicals in sweet potato may have significant antioxidant and anticancer activities. The antioxidant activity was directly related to the total amount of phenolics and flavonoids in the extracts. The additive roles of phytochemicals may contribute to its ability in inhibiting tumor cell proliferation in vitro.

Sweet potatoes are excellent sources of plant proteins with very low calories. Unlike other starchy root vegetables, it is very low in sugar, and in fact is a good blood sugar regulator.

As an anti-oxidant: Sweet potatoes have been found to contain a high amount of anti-oxidant, making it suitable in combating inflammatory problems like asthma, arthritis, gout, etc.

Diabetes: This fibrous root is suitable for diabetics’ consumption as it is a very good blood sugar regulator, helps to stabilize and lower insulin resistance.

Digestive tract, healthy: The significant amount of dietary fiber, especially when eaten with the skin, helps to promote a healthy digestive tract, relieving constipation and also helps prevent colon cancer.

Emphysema: Smokers and people who inhale second-hand smoke should regularly consume foods high in vitamin A as smoke has been found to induce vitamin A deficiency, causing a host of other health problems to the lungs.

Fetal Development: The high folate content is important and necessary for healthy fetal cell and tissue development.

Heart diseases: Consumption of this high potassium root helps to prevent heart attack and stroke. It helps maintain fluid and electrolyte balance in the body cells, as well as normal heart function and blood pressure.

Muscle Cramps: A deficiency in potassium can cause muscular cramps and greater susceptibility to injury. Make sweet potatoes a regular part of your diet if you exercise a lot, both for an energy boost and to prevent cramps and injuries.

Stress: When we are stressed, our metabolic rate rises, causing the body potassium levels to be reduced. By snacking on the potassium-packed sweet potato, it helps to rebalance the vital mineral, and helps normalize the heartbeat. This in turn sends oxygen to the brain and regulates the body’s water balance.

According to nutritionists at the Center for Science in the Public Interest (CSPI), the single most important dietary change for most people, including children, would be to replace fatty foods with foods rich in complex carbohydrates, such as sweet potatoes.

CSPI ranked the sweet potato number one in nutrition of all vegetables. With a score of 184, the sweet potato outscored the next highest vegetable by more than 100 points. Points were given for content of dietary fiber, naturally occurring sugars and complex carbohydrates, protein, vitamins A and C, iron and calcium. Points were deducted for fat content (especially saturated fat), sodium, cholesterol, added refined sugars and caffeine. The higher the score, the more nutritious the food.

The new generation
The research of Snake weed has found new interest for gatas-gatas (tawa-tawa) for its use in dengue, with increasing anecdotal reports of “cures.”
Decoction preparation: four grasp of gatas-gatas plants. Rinse. Put the
tawa-tawa into a pot of boiling water for one minute. Cool and Drink 1 to 1 1/2 glasses, every hour for 24 hours.

Uses
FolkloricCalled gatas-gatas because of the healing property of the milky juice.
Juice used for colics.

Decoction of fresh plant used as gargle for the treatment of thrusth.
Decoction of the root used to allay vomiting, chronic diarrheas, and fevers.
Root decoction also beneficial for nursing mothers deficient in milk: 4-5 glasses of tea.

Recent interests from the folk medicine grapevine
Dengue• A flurry of queries and web blogs, gatas-gatas has found new interest for gatas-gatas (tawa-tawa) for its use in dengue, with increasing anecdotal reports of “cures.”
• Decoction preparation: Cut roots off 5 to 6 gatas-gatas plants. Rinse. Put the tawa-tawa into a pot of boiling water for one minute. Cool. Drink the decoction, 1 to 1 1/2 glasses, every hour for 24 hours.

Studies• Antibacterial Activities And Toxicological Potentials Of Crude Ethanolic Extracts Of Euphorbia hirta: The study showed the ethanolic extract to inhibit the growth of test isolates except Salmonella typhi. The antibacterial effect was attributed to the presence of alkaloids, tannins and flavonoids which have been shown to have antibacterial properties. The results supports its use in traditional medicine.
• Euphorbia hirta leaf extracts increase urine output and electrolytes in rats: Studty suggests that the active components in the water extract of E. hirta leaf had similar diuretic effect as that of acetazolamide. The results validate its traditional use as a diuretic.
